To all whom it may concern:

Be it known that l, "Hefter W. CRANE, a citizen ci' the 'United States, residing at Philadelphia, inthe county of Philadelphia improvements in detachablev and inter-- changeable heels, and has for its object to rovide an exceedingly simple and effective evice of this character, which may be readily and .quickly attached to or detached romthe ordinary leather heel of a shoe.

'A further object of the invention is to.

provide a clam which may be readily secured to theA or inary leather heel of a shoe adapted to co-act with a locking plate carried vby the detachable heel, wherebythe lat'- ter may be securely `held in place without the likelihood of it becoming `accidentally detached. y

wth 4these ends in view this invention consists in the 'details of construction and f combination of -eleinents hereinafter set vforth and then .specifically designated'by the claims. -1

In order that those skilled yin the `art to which this invention appertains may under stand how to make land use `the saine, I will describe its construction in detail, referring by numeral to the accompanying drawing forming a part of this specification, in which- Figurel is a central longitudinal section of my improved heel showing the same attached toa shoe. Fig. 2, is a section at the i line 2-2 of Fig. 1. Fig. 3, is 'an inverted plan view ofthe clamp. Fig. Lisa side' elevation thereof. Fig. 5, is an` end "view:

thereof. Fig. 6, is a plan view of the lock- 'ing plate. Fig. 7, is a side elevation thereof; and Fig. 8, is an'end view thereof.

In carrying out my invention as here em- -bodied 2 represents the upper of an ordivso nary shoe, 3 the sole and 4 the heel. y 5 denotes the clamp comprising a cupped up bod portion 6 composed of the roof 7 and si e walls 8 from which projects the -liange 9 at right angles to said side walls :8. From the rooil 7 at the front end thereof projects the extension 10 at right angles to the roof, forming the front 4wall of the body iniwhich is formed 'theopening 11.

Projecting downward from the roof of the clamp'is a partition 12 in which ..-c formedqthe arms 13, lthe metal intermediate said arms being'bent yback toward the roof to form the angular' guide and rest 14'. The

partition 12 :liom'which the arms and guide or restsare formed is cut and stamped from 'the rooftf the body as plainly shown in Fig: 3,' .and saidroof also yhas a number of perforations 15 therein-through which pass the attaching nails 16 or their equivalent for fastening the clamp to the leather heel of the ordinary shoe.

17 is the locking plate having 'a' pair of parallel slits '18 `loi-ined therein projecting longitudinally from the front edge, thereby forming a `tongue 19 which is bent arcuate in shape to'forin a bowed spring having a pair otoppositefslits. 20 formed therein, onel of which projects from each edge of the tongueformed bythe slits 18.

In reducing the tongue from the lock- 'ing p ate 17, a Pair ofarms 21 are formed and these 'with 'the edge of the balance of the body ofthe locking plate forni a flange similar-to the flanger 9 of the clamp. From :the lockingplate are also formed a number of prongs 22 which assist in holding said lockingplate 4to the `detachable heel 23 here shown as being made of rubber and pro- ,v'ided in its. upper face with a cavity or Asocket 24 open at 'the front end and providedat the base of said cavity with a radi' -atingrecess 25 intofwhich extend thev edge' of the locking plate when the samedis placed in the 4cavity 24, and 'when vthe detachable zheel is formed of rubber,`said,locking plate is vulcanized theretoihy means of theprongs 22.' When the 'clam 'isjsecured to the leather heel of an' o inaryshoe, it will bev understod that afj--tletachableheel constructed as herein described may be readily attached tothe shoe by bringingv the'flange 9 vof the Aclamp and registration with the recess land'then sliding the detachable heel 23 into the position shown in Fig; 1, and it will be understood that astheK ,detachable heel is moved along thebowed spring tongue 19 will `conta/ct with the arms-"13 and be forced toward the body of the detachable heel until the slots 20 in the,A bowed spring tongue come into alinement with said arms 13, after which said tongue 19 will'return to its normal position, therebyv locking the detachable heel lupon the shoe.

To remove the detachable heel from the shoe it will be necessary te disengage the bowed spring tnguerl) from the arms 13 and be momentarily disengaged until the dej tachable heel can be drawn rearwardly sufficiently to bring the slots 20 out of alinement with the arms 13 at which time the detachable heel may be entirely separatcdfrom the shoe. To accomplish the last naine operation so that the detachable heel may be withdrawn from the shoe it vis unnecessary to use any special tool, for any relative slender instrument such as a nail may be inserted inthe opening 11 and between the spring tongue 19 and the guide' and rest 14, which will force the spring tongue down ward andv `disengage it from the arms 13.

l Of course I do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended' claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is

1. In combination with a lixed heel, a clamp comprising a cupped up body, ayflange projecting from the side walls of the body, an extension projecting from the front end of the roof of the body, said extension having' an opening therein, a partition pro- ,j ecting from the roof into the interior of the body, arms formed from said partition, a gulde and rest ormed from the artition intermediate thearms and incline toward the front edge of the roof, a detachableand interchangeable heel provided with a cavity open at the liront end and having a recess radiatingltherefrom, said recess arranged to situated 4heel for locking the latter upon the fixed receive t e flange of the\cla1np and means within the cavityof the detachable 2; In combination with a lixed heel, a clamp comprising a cupped up body, a flange projecting from the side walls of the body, an extension projecting from the front end of the roof of the b o'dy, said extension -having an opening therein, a partition projecting from the roof intothe interior of the body, arms formed from-said partition, a

guide ,and rest formed from the parti-tion intermediate the arms and inclined toward the front edge of the root', a detachable and interchangeable heel provided. with a cavity open at the front end and having `a recess radiating from the base of said cavity said recess arranged to register with the ange of the clamp when the detachable heel is drawn forward, and a locking plate situated within the cavity and projecting into the recess provided with means for engagement with the arms of the clamp to hold the detachable heel in position.

3. In combination with a fixed heel, a clamp comprising a cupped up body, a flange projectingfrom the side walls of the body, an extension projecting from the front end ofthe roof of the body, said extension h av- ,.ing an opening therein, a partition projecting from the roof into the interior of the body, arms formed from said partition, a guide and rest formed from the partition intermediate the 'arms andinclined toward the front edge of the roof, a detachable heel provided with a cavity open at the front end and having a recess radiating from the base of `said cavity', said recess arranged` to register with the flange of the clamp when the detachable heel lis drawn forward, and a locking plate carrieds by the ldetachable heel situated within the cavity and projecting into the recess, said locking plate comprising a body, a pair of parallel arms, a bowed spring tongue having slots therein and prongs, ,said slots in the bowed spring tongue adapted toregister with the clamp for locking the detachable heel upon the fixed heel.

In .testimony whereof* vI have hereunto aixed my signature 1n the presence of two subscribing witnesses.
